At an event at CES 2013 in Las Vegas, NVIDIA has just announced their brand new mobile processor - the Tegra 4 - which expands on the capabilities of their previous smartphone chips. It comes with 72 GPU cores in a new ULP GeForce graphics processor, plus four ARM Cortex-A15 cores making it the first quad-core A15 chipset available; the low power companion core also makes a comeback in this chip.
4G LTE is seen in the slide, but unfortunately it still isn't integrated into the chipset, meaning an additional chip is required that will potentially use more battery than the integrated modem in Qualcomm's chipsets.
In a demonstration at the event, a tablet with a Tegra 4 chipset inside is seen to blitz the Nexus 10 in a web-page loading test, completing the task in around half the time. The Nexus 10 has an Exynos 5 chipset with two Cortex-A15 cores, whereas the Tegra 4 chip has four, and this speed increase was stressed at the event. It was also stated (via a graph) to be faster than the Apple A6X chip in the iPad 4
